This invention relates to vehicles and has particular reference tosafety wheels for automotive vehicles employing pneumatic tires.

The sudden deflation of an automotive tire because of a blow-out orpuncture when traveling at a high rate of speed has been the cause ofmany serious accidents. Considerable effort ias been given to theproblem of safeguarding the automobile and its passengers during suchlll an eventuality, but much remains to be desired,

in so far as the results are concerned.

It is an object of this invention to provide a device which willovercome many of the diiculties heretofore encountered in devices ofthis li nature.

The principal object of the invention is the provision of a safetydevice which will adequately support the vehicle wheel and prevent thevehicle from swerving from its intended path in Q the event that a tireshould suddenly blow out.

An advantageous feature of this invention resides in the fact that whenin operation the safety load is carried by the device in a plane whichintersects the wheel center, thereby stabilizing the Vehicle by reducingthe thrust caused by the lowering of one wheel.

Another feature of this invention resides in the fact that the safetydevice is carried within the tire which renders it invisible andprotects :3.a it against the possibility of damage caused by stones orother obstructions in the road; and being so positioned the device willnot prevent the wheels from traveling in a rutted road and will notgather mud, stones and other foreign substances, as is common withsafety devices now on the market.

A further advantage of a safety device constructed and carried in themanner herein disclosed resides in the fact that if one section of 1.;the device should become damaged in any manner, that section can bereplaced without discarding the whole device.

Further objects and advantages of the invention will appear as thedescription proceeds,

ai reference being made from time to time to the accompanying drawingswherein:

Fig. 8 is a fragmentary side elevation of the flanged disc which formsthe principal part of the wheel structure.

Fig. 9 is a section taken on line 9-9 of Fig. 8.

Referring now more particularly to the drawings, it will be seen that inthe embodiment herein disclosed (Figs. l and 2) my improved safety wheelconsists generally of a disc wheel I0, a retainer ring II and the safetysectors I2 which are constructed and arranged as hereinafter describedmore particularly.

The disc Wheel I0 and the ring II are anged as at lila and IIa, whichflanges comprise the rim for retaining the tire casing I3 in position onthe wheel. The disc II] is provided with a central opening I4 toaccommodate the vehicle aXle, and with a plurality of holes I5 adaptedto engage the stud bolts (not shown) carried on the brake housing bymeans of which the wheel is secured to the vehicle.

The disc I the ring II and the sectors I2, have matched bosses I6 andholes I'l adapted to accommodate bolts I3 by means of which they aresecured together. The iiange Ilia is provided with an opening I9 toaccommodate the Valve stem 20 of the tire tube 2|.

The safety sectors I2 are preferably made of two stampings spot weldedtogether and flared at c the outer peripheries as at 22, to form ananchor for the rubber 23, which forms an intermediate cushion or tirefor the sectors when in use. Apertures 23a are formed in the flares 22so that the rubber may extend therethrough to prevent slipping. Thesectors I2 are further provided with dowels 24 arranged to engagecorresponding recesses 25 in the adjacent sectors to provide means tolock the sectors in alignment. The number of sectors I 2 which may beutilized in any wheel assembly depends upon the size of the pneumatictire it is desired to use, as in assembling the wheel and tire the widthof the sectors I2 must be less than the diameter of the central openingin the tire I3 so that the sectors I2 may r,

To assemble my improved safety wheel together with a tire, I prefer toplace the disc Wheel I0 on a bench or fixture,- with the flange IUadisposed downwardly, as shown in Fig. 2. I then insert the inner tube 2lin the tire casing I3 and inflate the tube slightly. The casing I3 andtube 2I are then mounted on the wheel I0, so that the bead of the casingI3 engages the ange Illa:r of the wheel I0 and the valve stem 20 engagesthe valve opening I9 in the flange Ina; The safety sectors I2 are theninserted into the tube 2I and casing I3 and adjusted so that the dowels24 of one sector engage the recesses 25 of an adjacent sector and thebolt holes I'I are in alignment with the bolt holes in the disc Il).l

The retaining ring II is then superimposed so that its bolt holes I5 arein alignment with those of the disc' I0 and sectors I2. The bolts I8are' then inserted and the assembly is secured with the nuts 26 and thewheel is ready to be secured to the vehicle and the tire fully inated.'Ihese operations are reversed to remove the wheel and tire.

Although I have herein disclosed the preferred form of my invention, itwill be understood that certain modications are possible in the construction and assembly, all of which are intended to be within thecontemplation of the invention and the scope of the appended claim.

Having described my invention, what I claim and desire to secure byLetters Patent is:

A safety wheel comprising a main body portion, integral means on saidbody portion for engaging the bead of a tire, bosses on said bodyportion, an annular member having bosses arranged to engage the bossesof said body portion, said annular member having tire engaging meanscorresponding with the tire engaging means of said body portion,y and aplurality of peripheral extension members detachably secured betweensaid body and said annular member, each of said extension membersconsisting of two plates welded together, the outer periphery of eachplate being ared to provide anchors for a resilient element.
